After you've looked around Christchurch for a day, hop on a cheap flight to Queenstown and extreme sports your bollocks off... Jetboating, bungy jumping, canyon swinging, luging, and - oh yes - partying. It's sort of the Interlaken of the southern hemisphere, I guess, but it's fun. And the people are TOP NOTCH. And you have to get a burger at Fergburger. Best. Burger. EVER.
